Abstract:
최근 다양한 휴대용 디지털 매체의 발전으로 시청자들의 멀티미디어 시청 환경이 공간적으로 확대되고 있다. 본 논문에서는 시청자가 VOD 서비스를 이용할 때 한 매체를 통해 시청하다가 이동을 위해 일시중지한 후 다른 매체를 통해 중지된 시점부터 다시 시청할 수 있는 VOD 시스템 제어구조를 제시한다. 그리고 이 제어를 위해 필요한 스트림 동기화 모듈과 시청 로그 기반의 세션 및 자원 관리 시스템을 제안한다. 특히, 시청자와 VOD 시스템간의 비디오 스트림 제어를 위한 세션별 VOD 서비스 연결 관리 시스템을 설계하고 시뮬레이션을 통해 VOD 서비스에서 Seamless 콘텐츠 연결 모델을 제시한다. As various portable digital devices are developed, the space of the TV audience is expanding. We propose a structure of broadcasting control in VOD service in which viewers can resume the viewing of digital broadcasting contents in different devices after they have stopped the viewing to move to another place. Then we design a session and resource management system of VOD for this control. In particular, we design the session management of each consumer and simulate the seamless VOD connection model.Keywords:

The video on demand (VOD) service can be implemented in a variety of ways called service policies. This paper investigates the characteristics of three distinct service policies, namely, on demand single cast, on demand multicast and phase multicast. The performance of the different service policies are evaluated and it was found that the on demand single cast policy is suitable for specialised viewing while phase multicast and on demand multicast can be used for broadcast video.

Recent technological advances have made multimedia on-demand services, such as home entertainment and home-shopping, important to the consumer market. One of the most challenging aspects of this type of service is providing access either instantaneously or within a small and reasonable latency upon request. In this paper, we discuss a novel approach, termed adaptive piggybacking, which can be used to provide on-demand or nearly-on-demand service and at the same time reduce the I/O demand on the multimedia storage server.

Video on Demand system is also known as interactive television-on-demand system. It is a two-way audio and video-on-demand system and realizes to play video program according to the user’s needs, which is based on the new concept of “user independent”. This paper briefly introduces the concept of video-on-demand system, streaming media transmission protocol, JMF features and structure and describes the overall structure and function of each part of the on-demand system.

This article introduces the concept of the Video on Demand System and Streaming Media Technology. Firstly, it analyses the current situation of the Video on Demand and the user requirement. The authors consider that Video on Demand System demands to be intelligent and take developing the Video on Demand System as an example. By using vs2005 as a development tool, we develop system using web services technology and Streaming Media Technology, and then probe some troubles and experiences coming across in the process to realize Video on Demand System based on Streaming Media Technology.
